To calculate the number of shingles, we first calculate for the total area of the roof of Janice's house. From the figure, we can calculate the area of the two shapes: pyramid and a rectangular prism.
A(pyramid) = lw+l√[(w/2)²+h²]+w√[(l/2)²+h²]
A = 208 m²
A(prism) = 2(wl+hl+hw)
A = 293 m²
Total area = 501 m²
Number of shingles she needs = 501 m² / 2.25 m² =<span> 223</span><span>

The first two graphs are D) and D).
For the last one (above), the triangles are not congruent (D), because C --> C' doesn't follow the same translation rule as A, B --> A', B'
Fee for distance = total fee - initial fee = 12.70-2.20 = $10.50
Now, for 1 mile = $1.50
for x miles = 10.50/1.50 = 7
So, tom travel 7 miles.
The answer would be -4.5/5. You would have to plot the number in between -2 and - 1 4/5. Hope this helps!
